TURNBUTTON-FASTENEB.

Application filed. February 26, 1921.

To all whom it may concern Be it known that l, GEORGE l'loLMEs, a citizen of the United States, and a resident of Newton Center, in the county of Middle sex and State of ll-las husetts, have invented an improvement in Turnbutton-Fastenors, of which the following description, in conne tion. with the accompanying drawing, is a specification, like reference characters on the drawing repri-isenting; like parts.

This invention relates to a fastener or turn-button of the kind commonly used for fastening the curtains of vehicles, and the invention consists in certain novel features or brstruction which will he hereinafter deswribed,

which conduce to 'low cost 01 construction end to strength and durability of the fasteners.

The fastener is of the kind in which the curtain or part to be fastened is provided with an oval hole having its reintorced by a groinet, which constitutes the movable member ot the fastener, while the standing; member consists of a base portion having a. shank of corresponding oval shape, and a correspondin y oval. button or head pivotally connect with the said base and adapted to be passed through the gromct and then to be turned to position to confine the groinet on the said shank, until the button is again turned to position to permit the gromet to pa oil over it.

Figure fl. is a front viewoi a fastener embodying the invention, showing the members engaged;

2 a sectional view, on line 02 of Fig. 1, of the standing member;

Figs. 3 and l side and end elevations of the shell which constitutes the outer part of the head or button proper, before assemblage;

l ig's. 5 and 6 corresponding views of the anvil or filling piece;

Fig. 7 a sectional elevation, and

l 8 an elevation at right angle thereto ot' the pintle or pivot shanlr of the button heed, also before assemblage; and

, Fig. 9 view of the underside of the assembled and completed button bead, ready for assemblage with the base as shown in Fig. 2.

The curtain or part to be fastened, a portion of which is shown at 2 in Fig. 1, has an elongated opening the margin of which is reinforced by an oval gromet 3 which may Epeeification of Letters Patent.

Serial No. 148,159.

be such as usually employed in fasteners oi the kind above referred to..

The standing member comprises a base portion having foot l adopted to be secured to the body of the vehicle, or partto which the curtain is to be fastened, and a shank 5 corresponding in shape to the open ing in the gromet as shown in 1, the said base portion preferably sing made of sheet metal drawn to the desired shape.

The button proper, or head, is composed in part of a shell 6 consisting of ahollow piece of sheet metal drawn to the proper shepe as shown Figs. 8 and l, and a pintle piece, which is in the form or"? a tubular rivet the base flange of which is of oval shape and fits within the open end of said shell, and is secured therein by having the edge portions 8 of said shell turned over upon said base as shown at 80 in Fig. 9.

In order to reinforce the button head and to support the base danneor" the pintle while the edges of the s iell are being bent into eneinent with it, a filling piece 9 is placed in the shell before the piutle piece is intro dured, said filling piece being shown as of hollow construction, shaped to it the inside of the button head. shell 6, but being closed SA oranvil for the base flange or the pintle while t e crises of the shell are being upset into on cement therewith, and in the subse uncut ones." on or"; mounting the button on the base poi on the standing member of the fastener.

By malrinp; the marginal port of the shell 6 with the pi 'ections 8 of the curved shape as shown the base flange of the pintle piece 7 is firmly engaged nhen said projections are upset or bent down. over it, as shown at 80 in Fig. 9. and is substantially covered except for the spaces 17. 18. which serve a purpose which willv be hereinafter referred to.

The button proper is assembled and completed by inserting; the tiller 9 in the shell 6 and then placing the base of the pintle piece '7 against the base of the filler 9 and then turning the marginal portions 8 of the shell 6 over upon the base of the pintle piece by the action of suitable dies.

The button proper composed of the parts shown in Figs. 3 to 8 united as shown in 9, as has just been described. is pivotally connected with the base piece 4, 5, by

the shanln of the part 'h which is passed through it perforation 12 in the end 01 the shank portion 5 of the base piece and s tter having a spring l4: placed thereoni has its end upset or neaded as shown at in Fig. 2, so thet said spring is interposed between the head 15 of the pintle and the inner sintace of the end of the shank 5, and thus causes the base of the bntton proper to be pressed firmly but yieldingly against the said shank end.

In order to provice for the intent the butt in the position in coincich the base shank 5 in position to pe .niit the gromet 3 to be passed over it for fastening; or nnfastening, or in the position right angles thereto to confine or fasten the gioinet as shown in Fig 1, the end the base shenl: 5 is provided with it raised rib 1t extending; the entire length oi the major .'s thereoii, except Where interrupted by the pintle hole 12, which ribcoopere es with recesses 17, 18, in the lower taco the button rope]; Which lie in the major and minor axes thereof.

The rib 16 by engagement with 17 normally holds the button in the base sh .T. 5, but when torcibp; l the spring 14: yields permitting the button to rise and be tuned so as to confine t groniet end at the end ot qnerter turn the recess l8 engage l tains the button in hoiding position untiforcibl turned therefrom.

The operation is the some as is usua with this type of fastener i Vhen the button is in coincidence e .h the shonl; 5 of the piece the r 'onieted button 10i9, of the tein is p sed over it on to the shank 5 as shown in F ej. i and the button is then t Mi to the position shown in rnis by the action of the rib E6 in its on the shank 5 while turning, erd droppin ieolt thereto when the notches 18 come into .i id meta and furthermore ale to scooine detached rroin the base 55 not lie piece as t ies happens when the pintlc is connected Wits l n by a screw threat engegcincnt n: somet ng' of that 31stnre, whether tie button heel is soiid or I claim:
